Bruner: Orthoptera from Africa. 131 



among the rank vegetation common in humid localities. Even many 

 of the more arid tracts also have their characteristic representatives 

 of the family. Many of the species are attracted to bright lights 

 after nightfall, hence are quite readily collected. Others may be 

 taken by beating and sweeping the foliage of trees and the herbage 

 growing at the borders of forests, groves, thickets, and the margins 

 of lakes and streams. Still others live upon the trunks of trees, on 

 ledges of rocks, and the ground, mimicking their surroundings in color. 

 At least fifteen distinct species of this family are represented in the 

 material now at hand, upon which I am reporting. 



Genus Arantia Stal. 

 Arantia Stal, Recens. Orth., II, pp. lo, 25 (1875); Brunner von Wattenwyl, 

 Mon. Phan., pp. 17, 136 (1878); Ib., Verh. K. K. Zool.-Bot. Ges. Wien, XLI, 

 pp. 8, 63 (1891); Karsch, Berlin. Ent. Zeitschr., XXXIII, pp. 422, 432 (1888). 



The genus Arantia is composed of twenty or more species of rather 

 large and showy insects, all of which are confined to Africa. While 

 bearing a general resemblance to certain of the larger and more robust 

 American forms, these insects possess certain distinctive characters of 

 their own, which readily separate the two groups. Only three of the 

 species are contained among the material at hand. 



74. Arantia rectifolia Brunner? 



Arantia rectifolia Brunner, I. c, p. 137 (1878); Karsch, /. c, p. 433 (1888). 



Two of the "katydids" among the material studied are referred to 

 Brunner's A. rectifolia with some hesitation. They are both females. 

 One of them come from Lolodorf, where it was taken by A. I. Good. 

 C. M. Ace. No. 5264. The other is from the Belgian Congo, collected 

 by Antisdel. C. M. Ace. No. 2315. 



75. Arantia orthocnemis Karsch. 

 Arantia orthocnemis Karsch, Ent. Nachr., XVI, p. 357 (1890). 



A single male from Lolodorf is assigned to A. orthocnemis Karsch. 

 It was taken by A. I. Good in August, 1913. 



76. Arantia mammisignum Karsch. 



Arantia mamtnisigniim Karsch, Stettin. Ent. Zeit., LVII, p. 332 (1896). 



There is a single female specimen of this large and attractive species 

 at hand. It also was captured by A. I. Good at Lolodorf. C. M. 

 Ace. No. 5264.
